Biphasic Granular Bioinks for Biofabrication of High Cell Density Constructs for Dermal Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a biphasic granular bioink (µInk) that enables 3D bioprinting of high cell density constructs for dermal regeneration. The bioink promotes cell proliferation, ECM deposition, and neovascularization, leading to tissue integration and reduced scar formation in vivo.

3D‐Printed Multidimensional Bionic Mg‐MC/PLGA Composite for Tailored Repair of Segmental Long Bone Defects

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops 3D‐printed Mg‐MC/PLGA scaffolds with varying Mg concentrations (0–20%). The 5% Mg scaffold shows optimal cytocompatibility, osteogenic activity in vitro, and significantly enhances bone regeneration in rabbits, improving bone volume and mechanical strength.
